Narrative:

From working with my own planes; with manufacturer's maintenance programs and with various maintenance facilities; I am familiar with tracking; anticipating and preparing for maintenance events which occur at varying schedules; whether by calendar date; flight time; or operating cycles; and sometimes in combinations. While maintaining the 'a' model king air at company abc; mr X presented a forecast of the next required items whenever the plane left his facility; and would call between events to verify compliance. When my company acquired the 'B;' the consensus was to use a beech service center for warranty purposes; which worked well for a number of items. Maintenance forecasting was coordination with the specialists there and an updated photocopy journal of all maintenance log entries was kept at that facility. To keep a local technician involved with the plane for short notice quick fix help if needed; I have him do as much light maintenance as practical at our hangar. He had taken delivery of new tires and brakes and we had a free day to install them. While doing so; I reviewed some items in the maintenance logs and noticed that I had not updated an entry on my outlook schedule and found the logbook entry to update it. This was for the altimeter/airspeed/transponder 2-YR test. The altimeter had been sent to an instrument shop and; when reinstalled; the log entry showed it was only checked; not fully tested. But I had our local technician look at it anyway; and he said the test was not complete. So I called the service center and they said the same thing and arranged to get it done the next day. I would be able to do a trip that evening but would have to stay out of some high traffic airspaces and cancel a trip the next day. Then about 1 hour later; the service center called again and said the plane was out of the '4 phase every 2 yr' requirement. Since company abc had kept me completely updated in the past; and; more recently; the 2-YR inspection requirement had been a non issue; I had not entered it as a checklist item on my outlook schedule; and missed it.

Title: A BEECH C90B HAD A PHASE CHK AND 'ALTIMETER; AIRSPD; TRANSPONDER' REQUIRED TEST EXCEED TIME LIMITS.

Narrative: FROM WORKING WITH MY OWN PLANES; WITH MANUFACTURER'S MAINT PROGRAMS AND WITH VARIOUS MAINT FACILITIES; I AM FAMILIAR WITH TRACKING; ANTICIPATING AND PREPARING FOR MAINT EVENTS WHICH OCCUR AT VARYING SCHEDULES; WHETHER BY CALENDAR DATE; FLT TIME; OR OPERATING CYCLES; AND SOMETIMES IN COMBINATIONS. WHILE MAINTAINING THE 'A' MODEL KING AIR AT COMPANY ABC; MR X PRESENTED A FORECAST OF THE NEXT REQUIRED ITEMS WHENEVER THE PLANE LEFT HIS FACILITY; AND WOULD CALL BTWN EVENTS TO VERIFY COMPLIANCE. WHEN MY COMPANY ACQUIRED THE 'B;' THE CONSENSUS WAS TO USE A BEECH SVC CTR FOR WARRANTY PURPOSES; WHICH WORKED WELL FOR A NUMBER OF ITEMS. MAINT FORECASTING WAS COORD WITH THE SPECIALISTS THERE AND AN UPDATED PHOTOCOPY JOURNAL OF ALL MAINT LOG ENTRIES WAS KEPT AT THAT FACILITY. TO KEEP A LCL TECHNICIAN INVOLVED WITH THE PLANE FOR SHORT NOTICE QUICK FIX HELP IF NEEDED; I HAVE HIM DO AS MUCH LIGHT MAINT AS PRACTICAL AT OUR HANGAR. HE HAD TAKEN DELIVERY OF NEW TIRES AND BRAKES AND WE HAD A FREE DAY TO INSTALL THEM. WHILE DOING SO; I REVIEWED SOME ITEMS IN THE MAINT LOGS AND NOTICED THAT I HAD NOT UPDATED AN ENTRY ON MY OUTLOOK SCHEDULE AND FOUND THE LOGBOOK ENTRY TO UPDATE IT. THIS WAS FOR THE ALTIMETER/AIRSPD/TRANSPONDER 2-YR TEST. THE ALTIMETER HAD BEEN SENT TO AN INST SHOP AND; WHEN REINSTALLED; THE LOG ENTRY SHOWED IT WAS ONLY CHKED; NOT FULLY TESTED. BUT I HAD OUR LCL TECHNICIAN LOOK AT IT ANYWAY; AND HE SAID THE TEST WAS NOT COMPLETE. SO I CALLED THE SVC CTR AND THEY SAID THE SAME THING AND ARRANGED TO GET IT DONE THE NEXT DAY. I WOULD BE ABLE TO DO A TRIP THAT EVENING BUT WOULD HAVE TO STAY OUT OF SOME HIGH TFC AIRSPACES AND CANCEL A TRIP THE NEXT DAY. THEN ABOUT 1 HR LATER; THE SVC CTR CALLED AGAIN AND SAID THE PLANE WAS OUT OF THE '4 PHASE EVERY 2 YR' REQUIREMENT. SINCE COMPANY ABC HAD KEPT ME COMPLETELY UPDATED IN THE PAST; AND; MORE RECENTLY; THE 2-YR INSPECTION REQUIREMENT HAD BEEN A NON ISSUE; I HAD NOT ENTERED IT AS A CHKLIST ITEM ON MY OUTLOOK SCHEDULE; AND MISSED IT.
